How can I click the Settings button on the top right corner of the screen, when the "GPS signal not found" red bar, or some other bar (such as the tutorial's "Find a Pokestop near you") is blocking it?
Below, I got two screenshots (not mine) illustrating the issue: the first one shows the red bar (on top of the game screen), and the second one shows the menu, with the settings button on top. Combine both, and you have my issue: the red bar goes above the settings button, making it impossible to reach. Tapping on top of it does nothing.

You can't tap on settings when the "GPS signal not found" banner is active. I've actually had this happen to me and wanted to change a setting, but could not. The banner, which is non-interactive, ends up being the focus of all touch events within it's area, preventing you from interacting with any controls that it covers.
In my case, simply restarting the application fixed my GPS issue so that I could alter my settings.
